Sci/tellera, Lam. — Tetyra, Fah. 

 Where the scutcllum covers tlie whole abdomen. 



S. linenla; Ci/nex /ineatu'i,L.; Wulf, Cimic, I, ii, 2. Length 

 four lines; red, long-itudinally striped with black above; black 

 points arranged in lines on the venter. Environs of Paris and 

 south of Europe, on flowers, the Umbe Hi ferae, particularly *. 



Pentamona, OHv. 

 Where the scutellum covers but a portion of the superior part of 

 the abdomen. This genus of Olivier forms five in the system of the 

 Rypgota of Fabricius; they are, however, as imperfectly characterized 

 as they are badly arranged. His ^/m, and Halys, are Pentatomap, 

 with a head more })rolonged and projecting in the manner of a snout, 

 and more or less triangular. Am.ong the species which he refers to 

 the first, that which he calls the acuminata, and which is the Pum.ise 

 a tele alongee of Geoffroy, appears to be essentially removed from the 

 Pentatomae by the antenn-,^e, which are covered at base by the anterior 

 margin of the thorax, and separated from it underneath, and by its 

 much larger scutellum, which approximates this Insect to the Scu- 

 telleree. In his Cydnus, the head, viewed from above, is wide and 

 semicircular; the thorax forms a transversal square, liai'dly narrower 

 before than behind, and the tibiae are frequently spinous. These 

 species remain on the ground. Oii\n-& numhcvi's. Xhe. Punaise noire 

 of Geoffroy. We might also approximate to them, as has already 

 been done by MM. Lepeletier and Serville — Encyc. Method. — certain 

 species in Avhich the sternum is neither carinated nor armed with a 

 spine. Such are the two following : 



P.ornata; Cimex omatus, L. ; Wolf, Cimic, II, 16. Length 

 four lines and a half ; figure of a rounded ovoid; red, multima- 

 culate ; head and Avings black. — On the Cabbage and other Cru- 

 ciferse. 



P. oleracea; Cimex oleraceus L.; Wolf, lb., II, 16. Length 

 three lines ; ovoid; bluish-green Avith a thoracic line, a dot on 

 the scutellum, and one on each elytron, white or red. 

 Other Pentatomae in Avhich the poststernum or mesosternum is 

 raised into a carina, or presents a spiniform point, would be distin- 

 guished by the generic appellation of Edessa, employed by Fabricius. 

 Several of the species which he includes in that genus present this 

 character. It is also visible in several of those which belong to his 

 Cimex, such as the two following Pentatomae : 



P. hcemorrhoidalis ; Cimex hcemorrhoidalis, L. ; Wolf., lb., I, 

 10. Length seven lines; ovoid; green above, yelloAvish beneath; 

 posterior angles of the thorax extended into an obtuce point ; a 

 large brown spot on the elytra ; back of the abdomen red, spotted 

 with black. 



* For the other species see Fabricius, Syst. Ryngot., genus Tclyru. According 

 to Dalman — Epliem. Entom., T. — his genus Canopus differs from the preceding one 

 in tne following characters: the body more inflated, slightly compressed, concave be- 

 neath, with the margin of the scutellum pendent over the sides ; no simple eyes ; 

 legs unarmed.
